DigitMarkerIconPainter class

A specialized painter for rendering digit contract markers on financial charts.

DigitMarkerIconPainter extends the abstract MarkerGroupIconPainter class to provide specific rendering logic for digit-based contracts. Digit contracts are a type of financial contract where the outcome depends on the last digit of the price at a specific time.

This painter visualizes various aspects of digit contracts on the chart, including:

  • The starting point of the contract
  • Individual price ticks with their last digit highlighted
  • The exit/end point of the contract

The painter uses different visual representations for different marker types:

  • Start markers are shown as location pins with optional labels
  • Tick markers are shown as circles with the last digit of the price inside
  • Exit markers are shown as flag icons with the last digit of the price

This class is part of the chart's visualization pipeline and works in conjunction with MarkerGroupPainter to render marker groups on the chart canvas.
